摘　　要：日盲区的存在,给近地探测240～280nm范围的紫外辐射提供了良好的背景。本文设计了一套成像型日盲紫外探测实验系统。从辐射能量传递的角度出发,借鉴凝视型红外搜索跟踪系统的分析方法,推导了紫外探测系统的探测距离模型。以氘灯为探测目标,在三种典型天气条件下对实验系统进行了探测距离实验。结果表明,采用探测距离模型的计算值和实验测量值有较好的吻合,为紫外探测系统的设计和性能评估提供了重要的理论和实验基础。The solar blind region provides a good background for the detection systems that work in the wavelength from 240 to 280 nanometers on the near earth surface. A set of solar blind ultraviolet imaging detection experiment system is proposed. From the point of view of radiation energy transfer, referring to the analysis methods of staring infrared search and track system, the detection range model of ultraviolet detection system was derived. With a deuterium lamp as the detection target, the experiment system and model were analyzed and validated in experiment under conditions of three kinds of typical weather. The result suggests that the calculated values are consistent with the practically measured values It provides an important theoretical and experimental basis for the design and performance evaluation of solar blind ultraviolet detection system .
